Specification of Letters Patent.

Patented llla'y 12, Hill.

Application filed August 14, 1913. Serial No. 784.692.

To all ie/mm it may (ion/ ern Be it known that l, A Nouuw l l, MAumvuLh. a citizen of the "United States, residing at Fort 'orth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvenu-nts in Beveledliule Molding Devices, at \vhieh the following is a specification.

My invention relates to improvements in matrices and more particularly to devires which are similar to inatriees which are used in linotype and intertypeor lineeasting niarhines. and whirh are'adapted to mold the small triangular rules whirh are used in printing and the objert is' to provide simple deviees whieh ("an be operated by matrix molding devires tor termin rules for printing purposes.

Another olriert is to provide simple molding devil-es for forming triangular rules on the edges of slugs similar to the line east slugs which are produced by linotypo or intertype or line c-astiilp marhines and to form the triangulaurules with such slender eonneetion t'o'the slugs that the rules .(an be readily broken from the slugs. Surh rules can be manufactured at very small cost at mueh smaller cost than the .printxing rules now in use. "When the rules are broken from the. edges of the slugs the slugs may be discarded and thrown into the inelting pot to be re-inel ted, the sole (llijit'll olf this invention being to obtain the triangular rules or other rules without asting; any great quantity of material. The slugs from which the rules are broken are not lost but are used again after being re-inelted.

Other OliJQClS and advantages will he 'lullv explained in the following description and the invention will be more pz'lrtieularly pointed out in the elailns.

lteferenue had to the armmpanying drawings whirh form a part ol? this appli eation.

.l igrure 1 is a side elevation ot a matrix moldingdevice lor molding); beveled rules. l ig'. 2 is a similar view with the hinge plates detached to expose the angular groove in which the bevel rule is formed. Fig. 25 is a broken pers 'iertive view of one of the rule molding derives. Fig. -l is a rross set:- tion taken substantially on the line 1.-- .r of l*i; 1. Fig. is a rot-s serlion ol a inolding devire showing the position ol' the die in whioh the rule is tornied. also showing the. position oi the slug to the rule and showing the hinge plates on each side of the slug. l igs. ll, 7, and H show enlarged views (it dies l'or making ditl'erent styles of bevel rules. Fig. l) is a broken view of the slug. showing the beveled rule partly detarhed therel'rom.

Similar eharaeters of reference are used to indicate the same parts throughout the several views.

i A bloek 1 having; the general design of blorks in eonnnon use, is provided. The blork i has the usual angular groove '12 and the eutout; 23 in the rear side. The rules, or the bevel rules, It are t'mtniedin dies -l and the dies 4. are mounted in the hlorks l by eutting a rhannel longitiuliiuilly through the l)l(J('l l, whieh channel has under rut edges 5 to receive the dies el. 'lelnporarv mo'ldin wings l3 and 7 are hingmlly eonnerted to the lilflt'h' l and these wings may be swung open so that the dies lcan be insorted and removed. The wing ('3 is pivot ally eonneeted lothe upper part of block l by the pivot bolts The wings t) have extensions f and the bolts 8 are extended through the parts or lips t). The wings 7 .have downward extensions 10 and a single pivot rod ll extends through the lips lli to hinge the wings T to the blork l. The rod It extends through parts l2 ot' the bloek l. The wings t3 are normally pressed against; the blot-k and the die by springs 1:5 whit-h have one end attarhed to the blorl; and the other end atlarhed to rods 1 The rod 11 whit-h atlarhes; wings 7 to the bloek is anrhored in parts lL ol' the blot-k l. The wing T has a, downwardly extending lip iii, and a spiral spring 17 presses against. that part ol' the lip lt' whirh is bark ot the pivot point or rod ll. that. is, the lip ll; extends 'l'arther down than the rod 11 so that the spring I? will press outwardly on lb" lip lt' and thus hold the wine 7 seenrely against, the body l. The wine's (S and T are then yieldingly oom-vied to the blork l and inelose a. die 4, ivhirh is mounted in a rhannel inside of the l)l()('l( l and is held in there by the under out edges of the ohannel. The wings ti and 7 thus serve to make the part of the metal which eonnerts the rule :5 with the slit; 2t) very thin so that the rule 3} (an be asily drlarlu-d llUlll the slug 3t).

'lhe dir- I may haie any suitable rhannel rut therein for molding rules of suitable de- Q L on sign. Figs. 6 to 8 show dies with different forms of grooves 21 therein. Any variety of printing edge or face may he formed on the rule by making the desired shape of groove in the die What I claim, is.,-

l. A rule molding mechanism comprising a bar having the general contour of a 2na1- triX and having a channel in one side with under cut edges, a die dovetailed in said channel and having the outer surface flush with the adjacent surface of said bar and having an angular groove intho on face thereof, and hinged members on said har inclosing said die and terminating with bevel edges in close proximity to each other over said angular groove.

. 2 A rule molding mechanism comprising a bar having the general contour of amatriX and having a channel in one side with undercut edges, a die dovetailed in said channel and having the outer surface flush. With the adjacent surface of said bar and having an angular groove in the outer face thereof, forntiing members hingcdly con-- nccted to said block and inclosing saiddic and terminating with beveled faces in close proximity to each other, and means for holding said members yieldingly against said die.

3. A rule molding mechanism comprising a bar having a flat face. and a channel in said face with undercut edges, a die dovetailed in said channel and having a groove therein, and plates hingcdly connected to said bar and inclosing said die and. terminating with beveled faces converging toward said groove and leaving a narrow space connecting the converging space he tvveen said plates and said groove.

l. A rule molding mechanism comprising har having a. flat face and a channel in said face with undercut edges, a die/dovetailed in said channel and having a groove therein and having the outer face flush With the face of said bar, plates hingcdly connected to said bar and terminating With beveled edges convergingtoward said groove and leaving a narrow space between the edges of said plates which connects the converging space between said plates with said groove, and springs for holding said plates space in said groove, and means for holding said plates yieldingly against the flat face of said bar and partly closing said groove.

In testimony whereof, I set my hand in the presence o'f'two Witnesses, this 2nd day of August, 1913.
